[0028] See also Figure 1-5 ,The utility model provides a technical solution:

[0029] A kind of adjustable clamping and fastening mechanism comprises an installation frame 1, a fixing block 2 is fixedly provided on the lower side of the installation frame 1, a fixing frame 3 is fixedly provided on the outer side of the fixing block 2, a winding roller 4 is rotatably provided on the inner side of the fixing frame 3, a strap 5 is rolled up on the outer side of the winding roller 4, the strap 5 movably passes through the fixing frame 3 and extends to the outside, and a hook 6 is fixedly provided on the outer side of the strap 5 located on the outer side of the fixing frame 3, a hanging ring 7 for docking with the hook 6 is fixedly provided on the outer side of the fixing block 2, the winding roller 4 movably passes through the fixing frame 3 and extends to the outside, and a turntable 8 is fixedly provided on the outer side of the fixing frame 3 at the outer end of the winding roller 4, a positioning bolt 9 is provided on the outer side of the turntable 8, the positioning bolt 9 threadably passes through the turntable 8 and extends to the inside, a plurality of positioning holes 10 for docking with the positioning bolts 9 are provided on the outer side of the fixing frame 3, and a plurality of anti-slip grooves are provided on the outer side of the turntable 8 to facilitate the rotation of the turntable 8, thereby facilitating the adjustment of the tightness of the strap 5 to meet different usage requirements.

[0030] Specifically, two groups of sliders 12 are movably provided on the inner side of the installation frame 1, and mounting plates 18 are fixedly provided on the outer sides of the two groups of sliders 12. The mounting plates 18 movably penetrate the installation frame 1 and extend to the outside, and arc blocks 19 are fixedly provided on the outer side of the installation plate 18 located on the outer side of the installation frame 1. The two groups of arc blocks 19 can conveniently clamp and fix the main trunk of the seedlings, thereby facilitating and quickly fixing the entire device.

[0031] Furthermore, an anti-skid pad 20 is fixedly provided on the outside of the arc block 19, and the anti-skid pad 20 is made of soft material. By providing the anti-skid pad 20, the friction between the arc block 19 and the main trunk can be increased to prevent the arc block 19 from slipping, thereby ensuring the overall stability of the device.

[0032] It is worth mentioning that a movable block 14 is movably provided on the inner side of the installation frame 1, and support blocks 13 are rotatably provided on both sides of the movable block 14. The two groups of support blocks 13 are rotatably connected to the two groups of sliders 12 respectively, and a movable rod 15 is fixedly provided on the outer side of the movable block 14. The movable rod 15 movably passes through the installation frame 1 and extends to the outside, and a handle 16 is fixedly provided on the outer end of the movable rod 15 at the outer part of the installation frame 1. By pressing the handle 16, the two groups of arc blocks 19 can be easily driven to move, thereby facilitating the installation or disassembly of the entire device and improving the convenience of operation.

[0033] It is worth noting that a slide bar 11 is fixedly provided inside the installation frame 1 , and the slide bar 11 movably passes through the two sets of sliders 12 . By providing the slide bar 11 , the sliders 12 can be easily limited, thereby improving the movement stability of the sliders 12 and the arc block 19 .

[0034] In addition, two groups of first springs 17 are arranged on the inner side of the installation frame 1, and one end of the two groups of first springs 17 are respectively connected to the two sides of the installation frame 1, and the other end of the first spring 17 is connected to the slider 12. The first spring 17 does not deform in the initial state. When the handle 16 is pressed to drive the slider 12 to move, the slider 12 squeezes the first spring 17, and the first spring 12 is deformed at this time. When the handle 16 is released, the elastic potential energy of the first spring 17 is released, thereby driving the two groups of arc blocks 19 to quickly clamp and fix the main trunk of the seedling, thereby improving the installation convenience of the device.

[0035] It has to be said that a second spring 21 is provided on the inner side of the mounting frame 1, one end of the second spring 21 is connected to the mounting frame 1, and the other end of the second spring 21 is connected to the movable block 14. The second spring 21 does not deform in its initial state. When the handle 16 is pressed to drive the movable block 14 to move, the movable block 14 squeezes the second spring 21, and the second spring 21 deforms at this time. When the handle 16 is released, the elastic potential energy of the second spring 21 is released, thereby driving the movable block 14 to move quickly and reset, thereby facilitating the arc block 19 to clamp and fix the main trunk of the seedling.

[0036] Working principle: First, press the handle 16 to drive the movable rod 15 and the movable block 14 to move. When the movable block 14 moves, it squeezes the two groups of support blocks 13 inside the installation frame 1. The support block 13 is squeezed and drives the slider 12 to slide on the slide rod 11. At the same time, when the movable block 14 moves, it squeezes the second spring 21, and when the slider 12 moves, it drives the mounting plate 18 and the arc block 19 to move and squeeze the first spring 17. Then, the installation frame 1 is attached to the outside of the main trunk of the seedling, and then the handle 16 is released. At this time, the second spring 21 is first reset and stretched, thereby driving the movable block 1 4 and the movable rod 15 move and reset, and when the support block 13 moves, the slider 12 is driven to move and reset on the slide bar 11, and the first spring 17 is also stretched and reset, so that the two groups of arc blocks 19 can be driven to clamp the main trunk of the seedling, which is convenient for fixing the installation frame 1, and then the binding belt 5 is pulled outward and wrapped around the grafted seedling, and then the hook 6 is hung on the hanging ring 7. At this time, the tightness of the binding belt 5 can be adjusted by rotating the turntable 8, and finally the positioning bolt 9 is inserted into the positioning hole 10, so that the tightness of the binding belt 5 can be determined, so that the seedling can be better fastened.
